In this far future, post-apocalyptic fantasy, Marcus learns there's only one way to rescind his exile. But the requirement is more than most men could bear. He fulfills his duty and is repaid with an extraordinary gift that takes him straight to the empress's bed.
This novelette is in the dying Earth tradition, a post-apocalyptic fantasy mixing magic with memories of genetic engineering. That premise made for a good start, although the author was trying too hard, cramming too much detail in and only getting himself muddled with POV and continuity errors. And then it gets crass, awfully puerile, as the climax of the story - if you’ll forgive me - is the protagonist being divinely granted a magical golden dick meant to save the world. This trash is beyond parody.
